The lobby is a sector that is located next to the entrance door .
Vestibule is the atrium or portal found at the entrance of a building . The term has its origins in the Latin vestibulum .
For example: "Last night there was a strange man in the lobby that scared me," "Some neighbors throw trash in the lobby and dirty the common spaces of the building," "I'm going to tell the manager that he has to change the light in the lobby."
Lobby in hotels, homes and other spaces
In hotels , the lobby is a large room located near the entrance and that connects with the reception, the cafeteria and other rooms for shared use: «If you wish, you can leave your luggage in the lobby and go up to get to know the room» , «When you finish showering, go down to the lobby and we'll meet you there» , “It's colder in the room than in the lobby; "I'm going to file a complaint."
In private houses and residences, the lobby is a small, covered space that connects the entrance with the rooms or a patio : "Please tell Sergio to wait for me in the lobby," "Stay in the lobby." "In five minutes I'll finish changing and I'm ready to go."
Theaters , cinemas, concert halls and other similar venues also have a lobby. These are rooms adjacent to the auditorium created as a rest or waiting area. The spectators are located in the lobby before the performance and during the breaks: "I go to the lobby to smoke a cigarette and return to the room" , "The theater was full: there were even people left in the lobby without being able to enter the room" .
The reception of a hotel is usually located in the lobby or next to it.
vestibular apparatus
The vestibular apparatus is closely related to the inner ear and the brain, and is responsible for very important functions for our development, such as balance, posture, and coordination of eye movement. It is worth mentioning that we speak of vestibular disorders when the ear or brain is affected by a disorder or an accident; Among the most common cases are Meniere's disease (characterized by tinnitus, nausea, and loss of balance ), positional vertigo, conditions caused by blows to the skull, and internal ear infections.
The inner ear, within which the vestibular organ is located, is located in the petrous bone, in the inner back part of the eardrum box; Among its components, the following can be distinguished:
- Bony vestibule : this is a bony chamber located inside the oval window, within which the utricle and the saccule (defined later) are located. At first glance, six walls can be seen, which are the floor, the upper one, the posterior one, the anterior one, the external one and the internal one (which contains the aqueduct of the vestibule).
- Bony semicircular canals : They are located in the upper and posterior external part of the vestibule. They have an appearance similar to tubes that curve, forming arcs, and flatten towards the sides. At each of its ends, you can see a hole, and one of them is wider than the other. Its path begins and ends in the lobby.
- Membranous vestibule : it is made up of the utricle (a vesicle of moderate size, inside which you can see an acoustic spot , where the utricular nerve divides) and the saccule (a small, rounded vesicle, which is located below the previous one, with which it communicates through the utriculosacular duct; another acoustic spot is seen).
- Membranous semicircular ducts : they are located inside the bony semicircular ducts and have three divisions (superior, posterior and external), which open above the utricle into five orifices, three of them wider than the remaining two.
